Science

Equipment: -Student -Field [space to run in] -Stop watch -Judge -Cones -Recording sheet - Excel [you can use this as a recording sheet if you have it] Aim: We wanted to investigate the effect of different types of exercise on our heart rate. In our class we have been learning about active schools, this is a program that teaches schools how to keep fit and healthy. In the active schools program we had a look at child obesity and what could happen to stuff like a heart attack. Then we look at the heart to see what will happen when you do exercise and different types of exercise. So we decided to do the heart rate for the science fair. Method: 1-Gather all the equipment you need. 2-Ask a friend [the judge] to set up the cones in a rectangle shape on the field. Set up the cones on the field 50ms by 100ms]. 3-Take your heart rate and record it on your recording sheet. 4- Ask two or three people if they can be control and do no exercise to look at the difference of the heart rate when you are finished. If they could time them with the stop watch for around 10 minutes. 5- Run around in the coned area for 10 minutes [make sure that your friend that is the judge times you to be exacted that it was 10 minutes. 6- When you are finished running around the coned area, record the changes of your heart rate on your recoding sheet 7- Make sure that you repeat the running in the coned area once a day five times a week. Hypothesis: If I am active for 10 to 15 minutes of cardiovascular exercise my heart rate will be 1500 beats a minutes
